What OS and FMP versions are you using?
Is this a windows machine that can't find it? Might Bonjour be missing from it?
Windows 8 and FM 13.
Bonjour was installed at the time FM13 was installed and it's been working fine.
I don't understand what's happened and why it finds it using "Open recent" but not using "Open remote"
Open Remote can show either Local Hosts or Favorite Hosts. Is it possible that you have Favorite Hosts up instead of Local Hosts in your dialog?
Can you see other hosted files from this problem computer?
You may not be able to test this, but if you can, what happens if you use open remote on a different computer? Can you see this file from that other computer?
There are no other files hosted on the main computer. Filemaker isn't installed on the third computer in the office.
I'm not in the office at the moment so I'll try connecting from my laptop using "Open remote" next time I'm in.
Thanks for your help and I'll post the result when I test from laptop.
You can always upload a small test file to the server and see if it appears when you use Open Remote.
These tests can help determine where to look next for the issue by isolating whether the issue is specific to the computer or the file.
OK, will try that too. Thanks again
